SW1 Connectors

SW1 Wire-to-Board/Wire-to-Busbar Interconnects incorporate COEUR socket technology which enables a high-current-carrying capacity in three sizes: 6.00mm (120.0A), 8.00mm (185.0A) and 11.00mm (300.0A) with a unique positive-locking design for secure mating.

Features and Benefits

Low Contact Resistance

The COEUR conical socket’s multiple contact beams offers low contact resistance and low voltage drop so there is minimal heat generation at the contact interface which results in higher current-carrying capacity compared to other contact designs.

Compact Design

The COEUR socket design enables mated interconnects that are lower in height, with a shorter length and narrower width than comparable solutions using hyperbolic sockets, while offering significant design flexibility in applications where space is limited.

 

User-friendly Positive Locking

The unique quick connect and pinch-to-release design helps ensure secure mating during system integration and helps prevent cable assemblies from later backing off pins due to shock, vibration or mishandling. It also eliminates the need for mounting hardware and reduces installation time and routine maintenance costs.

 

Positive Locking with 360° Cable Assembly Rotation

The stainless-steel spring clip latches onto a groove in the locking pin, allowing the cable assembly 360° rotation about the pin for easy cable assembly dressing during system integration.

Color coded receptacle housings:
Help to differentiate circuits and help prevent mis-mating when multiple cable assemblies are used on the same application

Reliable crimp geometry with high-quality 8-sided crimp profile:
Helps ensure minimal contact resistance at the interface between the wire and the crimp barrel, contributing to the system’s minimal heat generation and in higher current-carrying capacity compared to other designs

Multiple contact beams with optimal current-carrying capacity:
Provides low contact resistance, low voltage drop, and minimal heat generation at the contact interface

Quick connect/pinch-to-release cable assemblies:
Can be mated and locked or unlocked and unmated with a single hand by pinching the ergonomic ribs, unlike competitor products that requires a second hand to actuate their locking mechanism, offering enhanced functionality in tight spaces

Design flexibility:
Offers designers options for attaching pins to different substrates; Screw-mount pins attach to either printed circuit boards or busbars; Knurled press-fit pins attach to busbars

Overview

Power efficiency is critical to cost and safety management in the power intensive applications within energy storage systems. SW1 receptacles incorporate Molex’s proven COEUR socket, which with its multiple contact beams creates a large contact surface at the mating interface, resulting in low contact resistance and voltage drop which leads to minimal heat generation.

Dense electronic packaging demands a low mated height between a cable assembly and its printed circuit board or busbar. SW1 receptacle assemblies are about 1/3rd lower in height and 1/3rd shorter in length than comparable solutions using hyperbolic sockets. The z-axis mating configuration is designed to eliminate cable bend radius complications, making it an ideal solution for applications where space is constrained.

Identifying high-current, high-voltage interconnect that can attach to either printed circuit boards or busbars, accepts a wide range of wire gauges, and provides easy cable assembly management is a challenge. SW1 offers locking pins that can attach to either printed circuit boards or busbars. The SW1 receptacle assemblies accept wire gauges ranging form 2 AWG to 4/0 AWG. SW1’s unique positive locking design allows cable assembly to rotate freely about the locking pin axis after mating, simplifying cable assembly dressing.

I am interested in purchasing a cable assembly with SW1 connectors on both ends. Is Molex able to design and build double-ended SW1 cable assemblies?
Yes. Molex has a business segment that designs and builds cable assemblies. Contact your local Molex sales representative for details.

 

I am interested in purchasing a cable assembly with a SW1 connector on one end a non-Molex connector on the other end. Is Molex able to design and build cable assemblies with a SW1 receptacle on one end and a competitor’s connector on the other end?
Yes. While we love it when both ends of a cable assembly use Molex connectors, we understand that is not always the best solution. The business segment that designs and builds double-ended SW1 cable assemblies also designs and builds cable assemblies with a SW1 receptacle on one end and another manufacturer’s connector on the other end. Contact your local Molex sales representative for details.
